AUTOMOBILE-HORN.

To all whom it may concern-.-

Be it known that I, RAY H. MANSON, a

trolled by an electric current, the particular object of my inventionbeing to improve the hcrnsnow being manufactured and placed upon themarket.

' Another object of my invention is to produce a-shorthorn, such as isespecially adapted for useupon motor cycles. To accomplish this, I havearranged the apparatus in the rear part of the horn in a compactstructure, making it as-[iat as possible so as to shorten the horn.

Otherparticular objects of my invention will be better understood fromthe particular description which is tofollow. In this description I havedescribed one embodiment of my invention, which is illustrated in theaccompanying drawing.

This application is a successor of my application #695,386, filed May 6,1912, which application but not the invention disclosed therein isabandoned, in view of the present application.

Figure 1 is a section through an automobile horn illustrating myinvention, part of the resonator bein shown in elevation. Fi

2 is a rear end elevation of the partsshown in Fig. 1 with the rearcover removed.-

Figs. 3 and a are details.

Referring now to the drawing and to the embodiment of my inventionillustrated therein, at 7 I have shown a main frame piece or supportingmember, the main portion of which is flat, but the top portion of whichis dished by stanming or other means, as shown at 6, the side '5 beingshown inclined.- The bottom 8 of the dished portion contains an opening9 which in the form shown is eccentric with respect to the bottom of thedished portion. A sonorous member,

preferably a vibratile diaphragm'is mounted upon the edge of the dishedportion in any suitable way, the diaphragm being preferably concentricwith the dished portion. In the form shown, the diaphragm is clampedbetween the front 11 of the frame and the frame piece 7, the three partsbeing connected togetherby some suitable means, such as screws 12.- Anopening 13 is formed in the front 11 for the passage of sound waves, anda resonator 14 may be mounted in this opening. The lower part 15 of themain frame piece? constitutes a bracketfor connecting the horn to anysuitable support. Of course, this bracket may be separate from the framepiece. I prefer to mount an anvil 16 upon the diaphragm in order thatthe vibrating member may strike thereagainst to cause the diaphragm tosound a signal. This serves to protect the diaphragm and to concentratethe blow upon the geometrical center thereof. Electromagnetic meansincluding an armature 17 are employed. In the form shown I haveillustrated an angle armature- As shown, the armature constitutes whatis practically a right angle and may be cut from an ordinary piece ofangle iron, thus greatly reducing the cost of manufacture and improvingthe efficiency of the device. This armature is connected to the frame,and in the form shown, I employ a resilient member, such as a flatspring 18, connected by some suitable means, such as a screw 19 to thearmature. This may be connected to the limb 20 of the armature, which ispreferably substantially parallel to the diaphragm.

The spring is connected to the limb 20 adja cent the bent part of thearmature, and at the othenend the spring is connected to the main framepiece 7 by some suita-ble means, such as screws 21. In the form shown,-this connection is at the edge of the opening 9 in the bottom of thedished portion 3fthe main frame piece 7.

The limb 20 of the armature carries-the contact 22, preferably upon theback side thereof. The other limb 23 of the armature is adapted to beacted upon by electromagnetic means, such as electromagnets 1%. Thesemagnets consist of coils 25 which are mounted upon a core composed of aplurality of punchings 26. In the form shown, these punchingsareU-shaped and have a winding upon. each limb thereof. The unchingsi areconnected preferably to 'the bottom portion or back side of the framethrough suitable means, such as a support 30 and screws 31, the support30. serving to space the core from the frame. In the form shown, I haveillustrated the magnets as being connected to the edge of the opening 9,oppositethe connection of the armatureiofsuch frame piece. At 401 showaflexible member, here illustrated as a spring which is connected ateach end to the frame.

' Iprefer to connect this to the mainframe piece 7" upon the edge of theopening 9,

eing best mounted uponthebottom of the-- dished portion .Any suitableconnecting means, such as screws 42' and supports or spacing members 43are employed; 'This member carries a contact .45asshown in-.

termediate its ends, and in a position to e0 mediate member70 to one ofthe screws 42.

One end 71 of the member'70 is folded over and enters a perforation 72in the frame 7. This locks the screws together in a well known Way,preventing the screws 42 from shifting their position.

It will be obvious to those skilledin the art that numerous andextensive departures from the formandthe details of the ap paratus hereshown ay be made without departing fromthe spirit of the invention, thesame being herein shown solely for the purpose of illustrating onespecific embodr' ment of the invention.
